ZTE AC682 modem connects on Slax but cannot browse!!

This is a strange problem. I had a problem with the same modem, that is, ZTE AC682 (CDMA) in latest Ubuntus. But I have connected it in Ubuntu successfully. Now I am trying different distros. I have come accross Slax which is a Slackware based KDE distro. I love it so much because of its simplicity and its size (only 215mb). But having a problem connecting to the internet.

I have made a connect script which connects the modem automatically when run. It connects in Ubuntu (+other *buntus) just fine. But in Slax (v7.0.8, which has KDE 4.10.1) it connects as the ppp.log says, but I cannot browse in Firefox (v19).

I connect through something like: pppd call cdmadialer &
It should then connect the device ttyUSB0.

Just in case you have overlooked the obvious . . . . make sure your browser settings aren't set to 'Work Offline' .

Click on 'File' (Normally in the top left corner) and scroll down to 'Work Offline'. If it's checked, Uncheck it. Of course I'm not much of a google fan so it may be accessed differently on google.
On other distro's I have had to first Disable then re- Enable my network connection to overcome this type of glitch. I sure others have had similar issues. These are the one's I've overlooked from time to time only to feel pretty foolish later when I figured them out. Now they are the first places I check.

I am pretty sure it is not set to work offline. I have clicked the Try Again button a thousand times. The offline option should've been toggled. And besides, the ping should've worked if it was happening because of the offline option.

Yeah, I think it is so. There are many little things that get unnoticed.
How can I disable and re-enable the network connection? Should I stop some process and re-start it?

I've never used Slax, but in Ubuntu and it's derratives simply 'Right Click' the Connections Icon and uncheck the CDMA /Mobile Broadband option in the dropdown menu. then 'Lleft Click' the same Connections Icon and select the connection for your ZTE AC682.

I have also tried to disable NetworkManager:
chmod -x /usr/sbin/NetworkManager
reboot

But it did not work.

My modem in Ubuntu doesn't work with the network manager. May be it needs special parameters to connect which the network manager does not support.So I have to connect with pppd and with the modem,it provides some files for the /etc/ppp directory. And there's a chat.conf file which has many lines I don't understand:

First you need to use the full domain name "www.google.com" in your ping test. If you still get the "unknown host" error, then it means there is a problem with the server that translates domain names into ip addresses. Usually this server runs on your router.

The fact that you can successfully ping ip addresses shows that you have full network connectivity

I found out that ip-up is not there in the Slax's /etc/ppp directory. ip-up runs some commands after the connection is established. May be without it, the connection is established but some ip thingy did not run. So every request couldn't access the connection. So I copied ip-up, ip-up.d and also ip-down, ip-down.d from my xubuntu installation. I have also made the copied files executable. Then my connection seems to work fine!
